UNION, WEST HOSE-PIPE COUPLING.

SPECIFICATION forming part of Letters Patent No. 744,788, dated November24, 1903. Application filed February 2, 1903- Serial No. 141.529. (N0model.)

To all whom it may concern.-

Be it known that we, WILLIE NoBLE and BURTON L; WIGTON, citizens of theUnited States, residing at West Union, in the county of Doddridge andState of West Virginia,have

invented certain new and useful Improvements in Hose-Pipe Couplings, ofwhich the following is a specification.

This invention'provides a joint or coupling for pipe-sections,being'chiefly designed for hose to admit of connecting the same eitherto a hydrant or other Water-fixture-or joining sections when required toincrease the length of the hose for reaching any desired point.

The chief characteristic of the coupling is to dispense with threads andto enable the coupling to be quickly effected and the partsdisconnected, as desired.

The coupling comprises flanged members having corresponding notches inopposite edges of the flanges and interlocking projections to cause themembers to turn as a unit and a union for connecting the sections andfitted to one by a swivel-joint and provided with inner lugs to rideupon cam portions provided upon the flange of the other member, wherebythe sections of the. coupling are drawn together.

For a full description of the invention and the merits thereof and alsoto acquire aknowledge of the details of y construction of the means foreffecting the result reference is to behad to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modification, stillthe preferred embodiment of theinvention is illustrated in the acccompanying drawings, in which- 7Figure 1 is an elevation of a coupling embodying the invention. Fig. 2is a central longitudinal section thereof. Fig. 3 is a perspective viewof one of the coupling members. Fig. 4 is a similar view of the othercoupling member. Fig. 5 is a perspective view of the union. Fig. 6 is adetail perspective of the collar which facilitates the'connection of thesections. 7

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters. I I

The coupling members or sections are of similar construction and areflanged at'their inner ends. The member or section 1, provided withoppositely-extended studs 2, is flanged at one end, as shown at 3, thesame having notches 4 in opposite sides of the flange to admit ofclearing the inwardly-extended lugs of the union when coupling oruncoupling the sections. An annular groove is formed in the outer sideof the flange and receives a gasket 5 or packing-ring of rubber,

parallel cams 6 and '7, whereby the life of the coupling is increasedand the same made more stable.

The member or section 8 of the coupling is flanged at one end, as shownat 9, the same having notches 10 in opposite edges to admit of passingthe flanged portion into the rim portion of the union when assemblingthe parts. An annular rib 11 projects from the outer face of the flange9 to enter the groove of the flange 3 and bear against the packing ringor gasket 5. face of the flange 9'to interlock with the flange 3 of themember 1 by entering the notches 4 thereof, whereby the two members orparts of the coupling turn as a unit with reference to the union. Afterthe member or section has been fitted to the union it is prevented fromdisplacement by having a collar 13 secured thereto either by means of aclampscrew or analogous fastening. The collar 13 is cut away upon theedge adjacent to the union for about half its circumferential length, asshown at 14, to receive a lug 15,

projected from the rear or outer side of the loo Lugs 12 project fromthe union, whereby the latter has a limited rotary movement withreference to the members of the coupling.

The union 16 is of ordinary formation, comprising a rim portion havingan inner flange at one end to be confined between the collar 13 andflange 9, so as to make swivel connec tion with the member 8, upon whichit is mounted. Studs 17 project from opposite sides of the union forreception of a hose wrench or spanner, whereby the coupling anduncoupling of the joint is effected in the accustomed way. Lugs 18extend inward from the rim portion of the union at diametricallyopposite points and are adapted to engage with the cams of the member orsection 1. Said lugs 18 have two engaging shoulders to make contact Withthe cams (i and 7.

The members or sections of the coupling are adapted to be connected tothe parts to be joined in the usual Wayand are adapted to be coupled bypassing the flanged end of the member or section 1 into the rim portionof the union 16 and turning the parts to cause the cams to ride underthe lugs 18, whereby the members or complementary parts of the couplingare drawn together, as will be readily comprehended. Before fitting themember 1 into the union the latter is turned until the lugs 18 registerwith the lugs 12, after which the member 1 is inserted into the rimportion of the union, its notches 4 clearing the lugs 18 and engagingwith the lugs 12, whereby the two members become interlocked and areprevented from independent rotation d uring turning of the union tocomplete the coupling and draw the members or sections 1 and 8 together.

Having thus described the invention, what is claimed as new is- 1. Acoupling comprising flange parts, one of the parts having oppositelydisposed notches and cooperatin g cams extended from the respectivenotches,a union connected with the other part of the coupling member bymeans of a swivel-joint and having inwardlyextended lugs to pass throughthe notches of the first-mentioned coupling member and e11- gage Withthe cams thereof, lugs projected from the second coupling member andadapted to interlock with the notches of the firstmentioned member tocause said members to turn as a unit with reference to the union, andmeans for limiting the movement of the union, whereby thelatter-mentioned lugs are disposed so as to facilitate the interlockin gaction of the same with the notches.

2. In a coupling, corresponding members, one of the members havingopposite notches and stepped cam portions extended in oppositedirections from the said notches, and a union mounted upon the othercoupling member and provided with inwardlyextended lugs having a seriesof stepped shoulders for cooperation with the stepped cam portions ofthe aforementioned coupling member, substantially as specified.

A coupling comprising complementary members flanged at their inner endsand having notches in opposite edges of the flanges, one of the membershaving cams extended from the notches of its flange, a groove and rib inthe meeting faces of the two flanges, said groove receiving a packing, aunion mounted upon the other member and having a lug upon its outer orrear side, and inwardly-extended lugs upon its rim portion, a collarsecured to the member fitted to the union and having the edge portionadjacent to the union cut away to admit of a limited play thereof, andlugs extended from the face of the flange of the coupling member appliedto the union and adapted to enter the notches of the flange having thecam portions, substantially as described.

In testimony whereof we aiiix our signatures in presence of twowitnesses.
